Assumptions:Fix times with boxes provided above An average driving speed of 35mph (56km), airport <=> city centre.

An average speed of 400mph (644kmh) or longhaul, 550mph (885kmh) by plane.

Estimate assumes that airlines use required checkin arrival times for US airlines.

If you're flying from outside the US or you're not using airport checkin, or if you're using airport metros to get back and forth, travel time could be quite a bit shorter.All distances are "as the crow flies"
